SPECIFICATION forming part of Letters Patent No. 305,403, datedSeptember 16, 1884.

Application filed August 4, 1883.

T0 aZZ whom it may concern.-

Be it known that I, ALFRED WOOD, of Detroit, county of Vayne, State ofMichigan, have invented a new and useful Improvement in Knitting-MachineNeedles; and I declare the I following to be a full, clear, and exactdescrip tion of the same, such as will enable others skilled in the'artto which it pertains to make and use it, reference being had to theaccompanying drawings, which form a part of this Specification.

My invention consists of a knitting-machine needle constructed ashereinafter specified, and more particularly pointed out in the claims.

In the drawings, Figure 1 is an elevation of my needle, partly insection; and Fig. 2, an edge view with part of the needle broken away.

My invention is designed as an improvement upon the needleshown by me intwo former applications of mine for patents for improvements inknittinganachines, filed, re-

1 spectively, January 4, 1883, and April 27, 1883.

In those applications a needle was described as provided with a heelpivoted to the shank of the needle, and adapted to be thrown into or outof engagement with the needle-actuating cam. In use, however, I havediscovered that the said needle-heel was apt to shake loose, so as notto operate with certainty.

It is the object of my present invention to remedy this difficulty.

The drawings represent in enlarged form a knitting-machine needle, inwhich drawings- A indicates the needle-shank.

B is the foot of said shank, consisting of a plate secured thereto.

0 is the needle-heel, consisting of a slide. It is designed to engagethe needle-cam in all respects the same as described in my formerapplications before named; but instead of being pivoted to the shank theheel O is adapted to slide in a dovetail or undercut guideway formed inthe foot 13, which issecured to or formed on the lower end of theneedle-shank, a center-pin, O, and slot 0 being employed to prevent theheel from disengaging with said guideway.

D is a spring, which yields a frictional resistance against the heel, soas to hold the heel in position when it has been pushed down to engagethe needle-cam, and likewise (No model.)

hold it out of position when it has been disengaged from the needlecam,the tension of the spring being regulated by a screw, D. Of course thefrictional resistance may be afforded by a spring between the heel andthe foot B, as well as by the spring at the edge of the heel; and- Iwould have it understood that I do not limit myself in this respect toany particular kind of a friction device and location of the same, thatin the drawings having been found by me to be effective for the purpose.So, also, I do not limit myself to a dovetail connection between theheel O and foot B, for the heel may be simply held down squarely in agroove in the footand be held in place by the head of a retainingscrewlocated in the position of the pin G; or the heel might be fitted into aslot or mor- 7o tise made through the foot 13, so as to slide therein,the essential, feature of my invention being the combination, with theneedle-shank, of the sliding heel.

Having thus described my invention, what I 7 5 claim isu i 1. Thecombination, with the shank of a knitting-machine needle provided with aguideway, of a heel for engaging the needle-cam,

adapted to be slid back and forth and be adjusted in said guideway,substantially as described. g

2. The combination,with the shank of a knitting-machine needle providedwith a guideway, of a heel for engaging the needle-cam, adapted to beslid back and forth and be adjusted in said guideway, and means forexerting a frictional resistance against said heel, to hold it inadjusted position, substantially as described. o

3. The combination, with the shank of a knitting-machine needle providedwith an undercut or dovetail guideway, of a heel for engaging theneedle-cam, adapted to be adj usted in said guideway, substantially asdescribed.

4. The combination,with the shank. of a knitting-machine needle providedwith a guideway, of a heel, 0, adapted to be adjusted in said guideway,and a spring, D, to hold it in adjusted position, substantially asdescribed.

5. The combination,with the shank of a knitting-machine needle providedwith a guideway, of a heel adapted to be adjustedin said guideway, andprovided with a slot, and a pin secured to the shank and engaging withsaid for limiting the adjustment of said heel, the 10 slot, whereby themovement of the heel transspring D, and screw D, for holding the heel inversely of the shank is limited, substantially adjusted position,substantially as described.

as described. In testimony whereof I sign this specifica- 6. Thecombination,with the shank of aknittion in the presence of twowitnesses.
